+## 0.31.3 — 2026-05-30
+
+**Patch — admin Users tab: "Last seen" reads "Never" for unclaimed
+invites. Visual/logic only in `Admin.jsx`. A plain frontend rebuild
+applies it.**
+
+An admin-created invite row showed a real-looking "Last seen" timestamp
+identical to "Signed up," implying the invitee had visited when they
+hadn't. Cause: `users.last_seen_at` is `NOT NULL DEFAULT (datetime('now'))`
+(`migrations/001_users_and_audit.sql`) and the invite INSERT
+(`invites.py`) sets neither timestamp, so both default to the
+row-creation instant; `last_seen_at` only advances on a real
+authentication. Since an unclaimed invite has provably never
+authenticated (that unclaimed state is exactly what drives the
+"PENDING INVITE" badge), the Users tab now renders **"Never"** for the
+Last-seen cell of a pending-invite row instead of the misleading
+default. Signed-up (the invite-created date) is unchanged.
+
+Upgrade steps: none. **SHOULD** deploy as a normal code deploy.
